Growth & Zones
Grows as much as two feet a year for 10 years. Ideal conditions can allow growth up to 60' to 75', with a 45' spread.
USDA Hardiness Zones 3–8 (see map)
Bristle-tipped leaves turn red in the fall. The leaves have 7 to 11 waxy lobes. A good street tree, tolerates pollution and compacted soil.
Full sun is the ideal condition for this tree, meaning it should get at least six hours of direct, unfiltered sunlight each day.
Provides great fall color, with leaves turning russet-red to bright red.
Produces pale yellow-green catkins that appear at about the same time new foliage is expanding, typically April–May.
Yields acorns that are round and ¾–1" long with a flat, thick, saucer-like cap. Acorns are at the top of the food preference list for blue jays, wild turkeys, squirrels, small rodents, whitetail deer, raccoons and black bears.
Caring for your tree...
Pruning promotes tree health and allows gardeners to shape and control the size of the tree. Red oaks are not hard to prune when young, but mature trees can reach up to 90 feet, so those with tall red oaks should consider hiring a tree trimming service to reach the tall limbs.
Prune red oaks annually in the late winter to early spring when frost danger passes.
